Your consent
The first time you visit, we show a notice to accept or reject analytics cookies, with both options at the same level. Google Analytics does not load or send anything until you accept. We keep your choice for 13 months; after that we ask again.
How to change your choice
You can change it at any time from “Cookie preferences”, at the bottom of every page. If you withdraw your consent, we disable Google Analytics and delete its cookies. You can also delete cookies and site data from your browser settings.
